I'm not entirely sure as 'lemon' often implies adult content in fanfiction, but if we assume it's a non - adult take, perhaps Harry could dominate Petunia in terms of magical knowledge. Maybe he shows her the true power of magic and she has to accept his superiority in that regard.
It could be about Harry dominating Petunia in terms of influence. Maybe he starts to influence the Dursleys' household with his wizarding ways in a positive way. He could introduce new ideas and values that Petunia initially resists but eventually has to accept, thus Harry dominates in terms of changing the family environment.
Well, it depends on your definition of 'good'. Some might focus on the complex relationship between Petunia and the magical world in the context of Harry Potter, while others might take a more creative or off - beat approach. You really have to dig through different works to find one that suits your taste. There could be some that explore Petunia's character in depth, perhaps showing her envy of the wizarding world in a new light, or creating a scenario where she has a more positive interaction with the magical elements, which could be quite interesting to read.
One common theme could be the exploration of a complex family relationship. Since Petunia is Harry's aunt, there might be themes of family secrets and hidden emotions. Another theme could be the transformation of their relationship from a rather hostile one in the original story to something more nuanced in the fanfiction.
I'm not entirely sure as 'lemon' fanfiction often implies inappropriate or non - canon and unethical content. However, if we assume it's a more innocent exploration, perhaps it's a situation where Harry is forcing Petunia to face something she has been avoiding in a particular fan - created storyline. But this is all speculation based on the rather odd title.
It's inappropriate. The Harry Potter series is mainly aimed at a wide range of audiences, including young readers. Lemon fanfiction strays far from the family - friendly and magical essence of the original. Petunia, as part of the Muggle world related to the story, should uphold a certain standard, and using such fanfiction is not in line with that.
One common theme is redemption. Many fanfictions explore Petunia's chance to redeem herself for her past mistreatment of Harry. Another theme is family. They might not be a typical family, but the stories often focus on how they can form a bond. For example, in some, Petunia realizes her role as Harry's only remaining family member and tries to be better.
One common theme could be the exploration of Petunia's hidden feelings. Maybe she has some repressed emotions towards the wizarding world that are brought to the surface.
Fanfiction can cover a wide range of themes, but 'Harry Potter x Petunia' with a 'lemon' aspect is not something that aligns well with the overall tone of the original story. The series is mainly about magic, friendship, and the fight against evil. If you're interested in their relationship, look for fanfictions that explore their family dynamic, like how Petunia's jealousy and fear influenced her treatment of Harry, rather than 'lemon' ones.
The fact that Petunia uses Harry Potter lemon fanfiction might be a sign of her repressed feelings towards the magical world. In the books, she has a complex relationship with the wizarding side of things. By reading this type of fanfiction, she could be unconsciously trying to come to terms with her own connection to that world. It could also be that she's simply interested in the creativity of the fans, as lemon fanfiction often takes the original story in very unexpected and sometimes racy directions, and she wants to see how far fans are willing to go with their imaginations.
